DESCRIPTION:Hydro-elastic waves (HEW) appear at very large scale in the ma
 rginal ice zone where the ocean is covered by a thin layer of ice. The phy
 sics of HEW is dominated by the bending elasticity of the thin sheet cover
 ing the liquid\, but their propagation is much slower than plate (Lamb) wa
 ves thanks to the fluid inertia.\nIn this seminar\, I will describe our ex
 perimental approach of HEW. I will first focus on the typically parameter 
 range in which they can be observed at the laboratory scale. In a second s
 tep\, I will  show that HEW open promising possibilities for wave control.
  In particular\, I will present experimental configurations that allow for
  building an HEW based "optics"\, revisiting Snell's law\, geometrical opt
 ics and Fourier optics in an hydrodynamical experiment. Last\, I will desc
 ribe HEW propagation in periodically structured media\, revealing the emer
 gence of band gaps and Dirac points.
